Galera Cluster with MySQL 5.7 adding a new node

Hi all,

I’m attempting to add another node to my Galera Cluster running MySQL 5.7. Whenever I use 

sudo systemctl start mysql

It fails. The cluster it’s joining has a good 50gigs of data in it so it should execute a state transfer via rsync per the config but it never finishes and fails out normally after 5 ish minutes.

Is there a way to adjust the timeout? I’ve adjusted it within (/lib/systemd/system/mysql.service) to 7200 seconds. Am I missing somewhere else?

Thank you!

Hello friend!

Are you able to pull the service log and find out what it is reporting the problem to be after this occurs? I’m thinking that will be ideal in this case. Something like this should do it:

journalctl -u mysql.service –no-pager

Kind Regards,
Jarland
